Mercedes Benz B Class - buyer's guide
How much is a Mercedes Benz B Class worth?
Used Mercedes Benz B Class prices start from around £1,750 at UK dealers, with models ranging from 2006 to 2026. The exact value depends on the variant, year, mileage and condition - a high-spec AMG Line will be worth significantly more than a base model with the same age and miles.

Part-exchange, trade, or private sale - what's the difference?
The same B Class can be worth three different amounts depending on how you sell it:
- Private sale - typically the highest price, but you handle viewings, tyre-kickers and paperwork yourself
- Part-exchange - convenient when buying your next car, but dealers will offer below market rate to build in their margin
- Trade sale - quickest route to cash, but usually the lowest offer
Our free estimate tool shows what similar cars are listed for at dealers right now - a solid starting point whichever route you choose.
What problems should I look for on a Mercedes Benz B Class?

- Brake hose deterioration (all generations) (dangerous)

Can I check the service history of a Mercedes Benz B Class?
Yes. Our service history check pulls official records directly from Mercedes Benz's manufacturer database, showing:
- Every recorded service - dates, mileage and dealer location
- Work carried out at each visit
- Gaps in the service schedule that could affect value
If you're buying a used B Class, this is one of the most important checks you can do. A full service history typically adds 10-15% to a car's value.
How are these estimates calculated?
We crawl thousands of UK dealer websites daily and record what they're actually listing cars for. When you enter a reg, we match your car's exact variant, age and mileage against current and recent listings to produce an estimate grounded in real market data - not inflated book values or outdated guides.
